This application claims benefit of U.S. Provisional Application No. 61/155,622, filed Feb. 26, 2009. This application also claims benefit of priority under 35 U.S.C. §119 to French Patent Application No. 0858881, filed Dec. 19, 2009.

The present disclosure relates to a composition for dyeing or lightening human keratin fibers, comprising at least one oxidizing agent, a high content of at least one fatty substance and at least one nonionic surfactant comprising ethylene oxide in an amount ranging from 10 mol to 80 mol.

The disclosure also relates to a dyeing or lightening process using it and to multi-compartment devices or kits.

Among the methods for dyeing human keratin fibers, such as the hair, exemplary mention may be made of oxidation dyeing or permanent dyeing. For instance, this dyeing method may use at least one oxidation dye, usually at least one oxidation base optionally combined with at least one coupler.

In general, oxidation bases may be chosen from ortho- or para-phenylenediamines, ortho- or para-aminophenols and heterocyclic compounds. These oxidation bases may be colorless or weakly colored compounds, which, when combined with oxidizing products, can give access to colored species.

The shades obtained with these oxidation bases may be varied by combining them with at least one coupler, the at least one coupler being chosen, for example, from aromatic meta-diamines, meta-aminophenols, meta-diphenols and certain heterocyclic compounds, such as indole compounds.

The variety of molecules that may be used as oxidation bases and couplers allows a wide range of colors to be obtained.

It is also possible to add to these compositions direct dyes, which are colored and coloring molecules that have affinity for fibers. The direct dyes generally used may be chosen from nitrobenzene, anthraquinone, nitropyridine, azo, methine, azomethine, xanthene, acridine, azine and triarylmethane direct dyes. The presence of such compounds may enable the obtained coloration to be further enriched with tints or may enable the chromaticity of the obtained coloration to be increased.

Oxidation dyeing processes thus may consist in using with these dye compositions a composition comprising at least one oxidizing agent, for example hydrogen peroxide, under alkaline pH conditions in the vast majority of cases. The role of this oxidizing agent is to reveal the coloration, via an oxidative condensation reaction between the oxidation dyes.

It is desired that the oxidation dye should moreover satisfy at least one of a certain number of requirements. Thus, it should be free of toxicological drawbacks, it should enable shades to be obtained in the desired intensity and it should show the resistance to external attacking factors such as light, bad weather, washing, permanent waving, or aspiration and rubbing.

The dyes should also be able to cover grey hair and, finally, they should be as unselective as possible, i.e. they should produce the smallest possible color difference along the same keratin fiber, which generally comprises areas that are differently sensitized (i.e. damaged) from its end to its root.

The compositions obtained should also have good mixing and application properties, such as good rheological properties so as not to run down the face, onto the scalp or beyond the areas that it is proposed to dye, when they are applied.

Many attempts have been made in the field of hair dyeing in order to improve the dyeing properties, for example using adjuvants. However, the choice of these adjuvants is difficult insofar as they should improve the dyeing properties of dye compositions without harming the other properties of these compositions. For example, these adjuvants should not harm the keratin fiber-lightening properties and the dye application properties.

As regards processes for lightening keratin fibers, use may be made of aqueous compositions comprising at least one oxidizing agent, for example under alkaline pH conditions in the vast majority of cases. The role of this oxidizing agent is to degrade the melanin of the hair, which, depending on the nature of the oxidizing agent present, may lead to more or less pronounced lightening of the fibers.

One of the difficulties arises from the fact that lightening processes are performed under alkaline conditions and that the alkaline agent most commonly used is ammonia. The use of this compound may be frequent since it not only may enable adjustment of the pH to allow activation of the oxidizing agent, but also may cause swelling of the fiber, with opening of the scales, which may promote penetration of the oxidizing agent and increase the efficacy of the reaction. However, this basifying agent is very volatile, which may make it necessary to use it in relatively large amounts to compensate for the losses, the consequence of which is the inconvenience caused by the characteristic odor of this compound.

Accordingly, one of the aims of the present disclosure is to obtain compositions for the dyeing, for example for the oxidation dyeing, of keratin fibers, which do not have at least one of the drawbacks of the prior art.

For example, one of the aims of the present disclosure is to obtain compositions for the dyeing, such as the oxidation dyeing, of keratin fibers, with improved dyeing properties, which can achieve the desired lightening and which may be easy to mix and to apply, and which may not run but may remain localized at the point of application. As used herein, the term “improved dyeing properties” is understood to mean an improvement in the power/intensity and/or uniformity of the dyeing result.

Another aspect of the present disclosure is to propose keratin fiber-lightening compositions that do not have the drawbacks of those used with the existing compositions, these drawbacks being caused by the presence of large amounts of ammonia, and which may remain at least as efficient as regards the lightening and the uniformity of this lightening.

These aims and others may be achieved by the present disclosure, one aspect of which is thus a composition for dyeing or lightening human keratin fibers, characterized in that it comprises:

In at least one embodiment, the monoglycerolated or polyglycerolated C₈-C₄₀ alcohols correspond to the following formula:

RO—[CH₂—CH(CH₂OH)—O]_(m)—H

wherein R represents a linear or branched C₈-C₄₀, for example C₈-C₃₀ alkyl or alkenyl radical, and m represents a number ranging from 1 to 30 such as from 1 to 10.

As examples of compounds that are suitable in the context of the disclosure, mention may be made of lauryl alcohol containing 4 mol of glycerol (INCI name: Polyglyceryl-4 Lauryl Ether), lauryl alcohol containing 1.5 mol of glycerol, oleyl alcohol containing 4 mol of glycerol (INCI name: Polyglyceryl-4 Oleyl Ether), oleyl alcohol containing 2 mol of glycerol (INCI name: Polyglyceryl-2 Oleyl Ether), cetearyl alcohol containing 2 mol of glycerol, cetearyl alcohol containing 6 mol of glycerol, oleocetyl alcohol containing 6 mol of glycerol, and octadecanol containing 6 mol of glycerol.

For example, the alcohol may represent a mixture of alcohols in the same way that the value of m represents a statistical value, which means that, in a commercial product, several species of polyglycerolated fatty alcohol may coexist in the form of a mixture.

In at least one embodiment, the monoglycerolated or polyglycerolated alcohols are chosen from the C₈/C₁₀ alcohol containing 1 mol of glycerol, the C₁₀/C₁₂ alcohol containing 1 mol of glycerol and the C₁₂ alcohol containing 1.5 mol of glycerol.

For example, when present, the at least one additional surfactant is present in a total amount ranging from 0.1% to 50% by weight relative to the total weight of the composition, such as from 0.5% to 30% by weight relative to the total weight of the composition.

The composition may also contain various adjuvants conventionally used in hair dye compositions, such as anionic, nonionic, amphoteric or zwitterionic polymers or mixtures thereof; antioxidants; penetrants; sequestrants; fragrances; dispersants; film-forming agents; ceramides; preserving agents; and opacifiers.

For example, the above adjuvants may be generally present in an amount for each of them ranging from 0.01% to 20% by weight relative to the total weight of composition.

For example, the composition may comprise at least one mineral thickener chosen from organophilic clays and fumed silicas.

In at least one embodiment, the at least one organophilic clay is chosen from montmorillonites, bentonites, hectorites, attapulgites and sepiolites. In at least one embodiment, the at least one clay is chosen from bentonites and hectorites.

In another embodiment, the at least one clay may be modified with at least one chemical compound chosen from quaternary amines, tertiary amines, amine acetates, imidazolines, amine soaps, fatty sulfates, alkyl aryl sulfonates and amine oxides.

For example, organophilic clays that may be mentioned include quaternium-18 bentonites such as those sold under the names BENTONE 3, BENTONE 38 and BENTONE 38V by the company Rheox, TIXOGEL VP by the company United Catalyst, CLAYTONE 34, CLAYTONE 40 and CLAYTONE XL by the company Southern Clay; stearalkonium bentonites such as those sold under the names BENTONE 27 by the company Rheox, TIXOGEL LG by the company United Catalyst and CLAYTONE AF and CLAYTONE APA by the company Southern Clay; quaternium-18/benzalkonium bentonites such as those sold under the names CLAYTONE HT and CLAYTONE PS by the company Southern Clay; quaternium-18/benzalkonium bentonites such as the products sold under the names CLAYTONE HT and CLAYTONE PS by the company Southern Clay, quaternium-18 hectorites such as those sold under the names BENTONE GEL DOA, BENTONE GEL ECO5, BENTONE GEL EUG, BENTONE GEL IPP, BENTONE GEL ISD, BENTONE GEL SS71, BENTONE GEL VS8 and BENTONE GEL VS38 by the company Rheox, and SIMAGEL M and SIMAGEL SI 345 by the company Biophil.

For example, the fumed silicas may be obtained by high-temperature hydrolysis of a volatile silicon compound in an oxhydric flame, producing a finely divided silica. This process may make it possible, for example, to obtain hydrophilic silicas having a large number of silanol groups at their surface. Such hydrophilic silicas are sold, for example, under the names AEROSIL 130®, AEROSIL 200®, AEROSIL 255®, AEROSIL 300® and AEROSIL 380® by the company Degussa, and CAB-O-SIL HS-5®, CAB-O-SIL EH-5®, CAB-O-SIL LM-130®, CAB-O-SIL MS-55® and CAB-O-SIL M-5® by the company Cabot.

It is possible, for example, to chemically modify the surface of the said silica, via a chemical reaction generating a reduction in the number of silanol groups. For example, it is possible to substitute silanol groups with hydrophobic groups: a hydrophobic silica is then obtained.

For example, the hydrophobic groups may be:

-   -   trimethylsiloxyl groups, which are obtained, for example, by         treating fumed silica in the presence of hexamethyldisilazane.         Silicas thus treated are known as “silica silylate” according to         the CTFA (6th Edition, 1995). They are sold, for example, under         the references AEROSIL R812® by the company Degussa and         CAB-O-SIL TS-530® by the company Cabot;     -   dimethylsilyloxyl or polydimethylsiloxane groups, which are         obtained, for example, by treating fumed silica in the presence         of polydimethylsiloxane or dimethyldichlorosilane. Silicas thus         treated are known as “silica dimethyl silylate” according to the         CTFA (6th Edition, 1995). They are sold, for example, under the         references AEROSIL R972® and AEROSIL R974® by the company         Degussa and CAB-O-SIL TS-610® and CAB-O-SIL TS-720® by the         company Cabot.

For example, the fumed silica may have a particle size that may be nanometric to micrometric, for example ranging from about 5 to 200 nm.

Mode of Application

The three compositions detailed above were mixed together at the time of use in the following proportions:

-   -   10 g of composition A1 (Inventive according to the disclosure)         or A2 (Comparison)     -   4 g of composition B1     -   15 g of composition C

The pH of both resulting mixtures was of 9.9±0.1.

Each resulting mixture was then applied to locks of chestnut hair (tone height 4), at a rate of 10 g of mixture per 1 g of hair.

Each mixture was left at 27° C. for 30 minutes.

The hair was then rinsed, washed with a multivitamin shampoo and dried.

Colorimetric Results:

The coloring of the hair was evaluated visually and read on a Minolta spectrocolorimeter (CM2600D, illuminant D65, angle 10°, SCI values) for the L*, a*, b* colorimetric measurements.

In this L*, a*, b* system, L* represents the intensity of the color, a* indicates the green/red color axis and b* indicates the blue/yellow color axis. The lower the value of L, the darker or more intense the color. The higher the value of a*, the redder the shade; the higher the value of b*, the yellower the shade.

The variation in coloring between the colored locks of natural/permed white hair which is untreated (control) and after treatment are defined by ΔE* according to the following equation:

ΔE*=√{square root over ((L*−L ₀*)²+(a*−a ₀*)²+(b*−b ₀*)²)}{square root over ((L*−L ₀*)²+(a*−a ₀*)²+(b*−b ₀*)²)}{square root over ((L*−L ₀*)²+(a*−a ₀*)²+(b*−b ₀*)²)}

In this equation, L*, a* and b* represent the values measured after dyeing the natural/permed hair comprising 90% of white hairs and L₀*, a₀* and b₀* represent the values measured after dyeing the natural non-permed hair comprising 90% of white hairs.

The greater the value of ΔE, the greater the difference in color between the control locks and the dyed locks.

As shown in Table 1 below, the mixture according to the disclosure, comprising more than 25% by weight of fatty substances, gave a better lightening effect than the comparative composition comprising less than 25% by weight of fatty substances.
